Fix
You receive a non-

similar to this after
performing the
tar
command:
tar: /dev/st0: Wrote only 0 of
10240 bytes
tar: Error is not recoverable:
exiting now
The tape device has a
blocksize
set to a parameter
value other than
0
.
Use
mt
to set the
blocksize
to
0
so the tape
drive can operate in variable blocksize
mode. Execute this command:
# mt -f /dev/st0 setblk 0
Note:
st0
is used as the device node for
this example only; be sure to use the
correct
mode0
node.
No information is returned
when you execute the
command
# rpm -qa | grep mt-st
to verify
mt-st
is installed.
mt-st
is not installed.
Install
mt-st
(see
Installing mt-st
on
page 17).
No information is returned
when you execute the
command
# rpm -qa mtx
to verify
mtx
is installed.

is not installed.
Install
mtx
(see
Installing mtx
on page 21).

st
module name not found.
st
module is not loaded.
Load the
st
module. Consult your Linux
manuals for instructions.
The

Create the device nodes.
Use the
mknod
commands described in

on
page 16 and
Creating No-Rewind Device
Nodes
on page 16
Refer to the following documentation for
more detailed instructions:
